JOHN L. J UDSON AND WILLIAM A. OOGSWELL, OF ROCHESTER, NEW YORK,

'ASSIGNORS TO JUNIUS JUDSON 8c SON, OF SAME PLAGE.

GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 254,775, dated March 7, 1882.

l Application filed May 31, 1881. (No model.)

To all whom 'it may concern:

Be it known that we, JoHNL. J UnsoN and WILLIAM A. UoeswELL, both of Rochester, Monroe county,'New York, have invented a certain new and useful Improvement in Governors and we do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure lis an elevation, partially in section,

f a governor showing ourimprovement. Fig. 2

is a plan of the same, one ofthe balls being in section to show the cross-bar and its attachments.

Our improvement relates to what is known as the Judson 7 governor; and it consists of an arran gementofsprin gs and adjustable crossbars connecting the balls, constructed, arranged, and operating as hereinafter more fully described.

The governor is of ordinary and well-known construction, and does not require special-description. j

A A are the balls, which are iattened on `the sides, instead of heilig spherical, asis ordinarilythe case. In these balls are made horizontal slots or passages a a, extending through the balls, and being of considerable width, as shown. In these slots rest cross-bars B B,

through which pass screws C G, turning looselyr in the ball. The cross-bars forni nuts, and as the screws are turned said cross-bars will be moved ont or in, as the case may be. The ends of the cross-bars project some distance beyond the sides of the balls, and have hooks b b formed tl1`ereon, as shown in Fig. 2.

D D are coiled springs, made of light springwire, and having loops c c, which rest on the hooks b b, and the springs thus form a connection between the cross-bars on opposite sides of the balls.

It is found that cross-bars passing through slots in the balls, projecting on opposite sides and made adjustable forward and back, are convenient attachments for the springs, as the latter can be attached and removed with the greatest facility, and the tension can'be adjusted with great accuracy on both springs at once, so that the governor can be adapted to the work for which it is intended without difculty.

It' desired, one only of the balls may be provided with the slot and adjusting-screw, the cross-bar being made xed and stationary in the opposite ball.

By the use of two coiled springs on opposite sides ofthe balls connected directly from one ball to the other, and adjustable to different tensions, the action is balanced, and the balls, while speeding the governor, (or requiring an increased speed before commencin gto rise,) are at the same time much more sensitive to variations than the ordinary weighted balls, or those balls which are attached to elliptic or other flat springs whose tension increases by centrifugal action.'

Bythe use ofsprings extending directly from ball to ball the tendency is to reduce the friction on the pivots of the arms, as the springs draw against the centrifugal action and draw up toward the pivots, instead of throwing out against the pivots, as where weighted balls are used.

We disclaim springs connecting the balls and attached to bearings on top of the balls.

What we claim as new is-V In a governor, the combination, with the balls A A, of cross-bars B B, attachedto the balls and made adjustable forward and back, and coiled springs D D, connecting the crossbars, as shown and described, and for the purpose specified. A

In witness whereof we have hereunto signed our naines in the presence of two subscribing witnesses.
